Example B1: run Beam On error


I was finally able to run example 1 and build the geometry. However, I am having trouble with an error after running the command /run/beamOn 10

After running the executable, I get this output:

The output I am getting after running the command /run/beamOn 10 is this:

Idle> /control/verbose 2
/control/verbose 2
Idle> /tracking/verbose 1
/tracking/verbose 1

Thank you!!!

Just as an update, I was able to solve this issue by redifining all environment variables as stipulated in the post-install setup guide. Hope this helps someone!

It seems to me that you can’t read the EM libraries. I think you should check the reading permission of the files of the EM libraries.
